1. Introduction

Thanks for purchasing our company’s power inverter of SHI series.

The product is a sine wave power inverter which can convert

12V/24V/48V DC to 220V AC (50Hz/60Hz) based on high performance

DSP full digital and intelligent design. It has the features of high

reliability, high efficiency, low weight, small volume, full protection

functions, easy installation and operation. The inverter can be applied in

many fields especially for solar photovoltaic power system.

Powerful DSP digital and intelligent design

3. Important Safety Instructions

As an AC power supply equipment, the inverter’s output voltage is

with the same level as that of household power plug. Mind the AC output

terminals, or you may get an electric shock!

Attentions:

Connect the DC input according strictly to the requirement. The

power inverter has a relatively wide input range, but too high or too

low input may cause problems even destroy the inverter.

Do not expose the inverter to humid, flammable, explosive or dust

environment. Do not install the inverter in airproof location and keep

enough space around the inverter.

Make sure the air ventilation clearance around the inverter is more

than 10cm, for when the inverter works continuously its surface may

became very hot. Keep away from the material or device which may

suffer from high temperature when the inverter is working.

Connect the load devices to the AC output outlet, then the DC input.

Make sure both the input and output connects are correct, switch on

the inverter first and then turn on the load.

Do not connect the battery charger or similar devices to the input

terminal of the inverter.

Do not put the inverter close to the open lead-acid battery because the

sparkle in the terminals may ignite the hydrogen released by the

battery.

Do not attempt to repair the fault inverter yourself, otherwise it may

lead to a serious accident. Please connect the manufacture’s engineer.

4. Inverter Operation

Connect the input and output terminals accurately by referring to the

previous chapter. Use the ON / OFF switch on the front panel to turn the

power on. Turn AC loads on one by one after the output of the inverter is

normal, in order to prevent protections resulted from the surge power.

Set the power switch to the OFF position.

Insert the load’s plug into the inverter’s output outlet.

Connect the battery(‘+’ terminal with red line,’-‘ with black line). Do

not connect them by contraries, or it will damage the power inverter.

Switch the inverter to ON and then turn the loads on one by one.

Check the operation state of both power inverter and loads. ‘Green’

of the LED indicator means the state is normal.

If there are different loads, it is suggested that turn on the load with

large startup current first, such as television, then turn on the load

such as lamp when the inverter works stable.

If the failure LED indicator is ‘Red’ and the buzzer alarms or no

output when you turn on devices, switch off the loads and power

inverter immediately. Check the system by referring to the

troubleshooting guide. Turn on the devices again according to the

operation methods after the failure is removed.

Protections

Output Short Circuit Protection

The inverter switches off the output immediately when the

connecting load is short. Then it recovers the output automatically

after delaying 5 seconds. If the short circuit status still remains when

the inverter tries to recover for three times, you should clear the load

faults then restart the inverter manually or by remote mode.

Overload Protection

The inverter switches off the output after working for 30, 5 and

1.5 seconds when the load power is over 125% of rated value, 150%

of rated value and 200% of rated value respectively.

Input Low Voltage Protection

The output is switched off when the input voltage is low than

90% of the rated value.

Input Over Voltage Protection

The output is switched off when the input voltage is over than

133% of the rated value.

Fault Protection

The inverter will shut down when the output voltage falls below

176V, or above 264V or when the inverter has inner fault.

12

Over Temperature Protection

The inverter will shut down when the power device’s

temperature is over 75℃.

Fan Ventilation

The fan runs when the output power is more than 5% of rated

value.

6. Troubleshooting

WARNING：

High voltage is inside the inverter, do not open or disassemble

it! Attempting to service the unit yourself may cause the risk of

electrical shock or fire!

Problem Possible Cause Solution

Input LED

blink, fault red

LED slow blink

Input voltage is

too high or too low

Measure the input voltage. The

inverter recovers when the

input becomes normal.

Load LED

blink, fault red

LED fast blink

Overload or load

short

Check out if the AC load is

within the rated power or

whether there is load short.

Fault orange

LED fast blink

Over temperature

inside the inverter

Improve the quality of

ventilation and do not block

the vents. Restart the inverter

when it is cool down.

Fault red LED Inverter

abnormal

Remove all the connected

plugs then restart. If inverter

works well, please check the

load and line. If the LED

keeps red, the inverter has

inside faults and should be

returned to the factory
